ltacliators; and do hereby declare the fol lowing to he a ztull, clear,and exa zt de scription of the invention, such as will enable othersskilled in the art to which 1t appertains to malre and use the same,reien once being had to the accompanying drawlugs, and to the charactersof reference marked thereon, which form a part of this specification.

This invention relates particularly to heating means tor the radiatorsof automobiles to p-revenlua freezing of the same and also to maintain acirculation within the water cooling system of an automobile en.- gincwhen the same at rest.

7 The object of my invention is the provision of an in'iproved device ofthis character which is simple, cheap and inexpensive in itsconstruction and. which may be used without danger of fire.

The invention is described inthc following specification, and while, inits broader aspect, it is capable of embodiment in numerous forms,preferred embodimeiu;

thereof is illustrated in the acconuganying drawings, in which Figure 1is an elevation of a portion of an automobile with my inventionconnected to the cooling system of the engine. Fig. 2 is an enlargedelevation of the heater with a part broken away. Fig. 3 is a section onthe line 33 in Fi *2, and Fig. l a perspective view of the electricheating -elcmcnt removed from the heater.

Referring to the drawings, 1 designates an automobile engine of theii'lternal combustion type, 2 the customary radiator and 3 the heaterembodying my invention, which heater is attached to the engine casing orotherwise suitably mounted in position to be interposed in thewatercirculating system between the radiator and the engine.

The heater 3 comprisesa drum which may be of circular, elliptical orother form in cross section, and anv internal casing which cooperateswith the external casing 5 to form a water circulating chamber 6. Thecental opening or passage 7, which is formed by the inner casing #l, isopen at top and bottom thereof permit a circulation of air therethrough,and a suitable heating means 8 is disposed therein. lhc heating means 8,in the present instance, comprises an electric heating element, which issupported in suspended relation. within the passage 7 by a top plate 9,which rests on and is screwed or otherwise suitably secured to the upperend 01": the drum. The

lower end of the heating element is provided with laterally projectingspring fingers or flanges 10. which engage the opposite side walls ofthe passage 7 and prevent lateral movements of the heating clement insaid passage.

The outlet manifold 11 of the water circulating system, which manifoldis in communication-with the water jacket space of" the enginecylinders, is connected to the upper end of the radiator 2 through theme dium of the upper end portion of the heating drum chamber 6 and aflexible tube 12, said tube being preferably split and having oneportion connected to the interior of the heating chamber 6 through themedium 0i a nipple 1.3 on the drum and the other portion of said tube,which forms the outlet from the chamber, being connected to a nipple 14:or the drum. The intake water circulating manifold 15 for the enginecylinders has connection with the interior of the drum chambcrG at thelower end thereof through a nipple 16, and a. flexible tube 17 openscomn'iunicat-iou between the lower end portions of the radiator 2 anddrum chamber 6, bemg connectedto a nipple 18 at the lower end of theheating drum.

it is evident that a generating oi heat within the drum passage 7 willcause a heat ing of the water within the drum chamber 6 and create aforced circulation of the water through the circulating system. Atmaterial advantage. is obtained by intcrposing the water chamber 6 ofthe drum in both the outgoing and ingoing passages of the enginecirculatingkystcm, as this, under drdinary conditions, will create acirculation through the entire circulating system, namely, the engine,the radiator and the connecting passages, or it the circulation. ineither the radiator or the engine should happen to be stopped anindependent circulation is set up through the other member. Forinstance, should circulation through the radiator be stopped from anycause, the heating oi the water within the heater chamber 6 cause acirculation to take place through the engine, so as to prevent freezingtherein and a consequent cracking of the engine casing.

If an electric heater is used an electric plug may be inserted into asocket 19 on the plate 9.

It is evident that the heater may be removed from the engine during,Warm Weather and the adiator tubes 12 and 17 connected directly to therespective engine manifold.

I wish it understood that my invention is not limited to any specificconstruction arrangement or form of the parts, as it is capableofnumerous modifications and changes Without departing from the spiritof the claim,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination with a radiator and an internal combustion engine of anautomobile, in water circulating communication one with another, of adrum having an internal heating chamber open at its top and bottom, andsurrounded with a water circulating chamber having its top portionprovided with an opening in connection with the out let of the enginecirculating system and also culate between the engine and radiator, or-

independent circulation may be set up through the engine and waterchambe and through the radiator and water chamber, and an electricheating unit removably dispo ed in the inner chamber of said drum andclosing the top opening of said heating chamber.

In testimony whereof, 1 have hereunto signed my name to thisspecification.
